## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | `mcp__stays__cancel_booking` `mcp__stays__request_booking` `mcp__stays__search_stays` |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Deletes or cancels (2)

Removes, cancels or revokes something. Claude Code: deny.

### `cancel_booking`

- The name "cancel_booking" says "cancel": a word for removing or ending something.
- The description says "cannot be undone".
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Cancel a Bookd booking for the guest. First call with confirm=false to see the refund under the property's policy and tell the guest; only call with confirm=true after the guest explicitly agrees. Needs the booking_id and the email used to book. confirm=false changes nothing. confirm=true cancels for good (it cannot be undone): it releases any card hold or refunds under the policy on the property's own Stripe account, frees the dates (and cancels it in the property's booking system when it is connected), and emails the property and the guest.
```

### `request_booking`

- The name "request_booking" says "request": a word for a change.
- The description's first verb is "send": a word for sending, and what is sent cannot be taken back.
- The server marks it destructive (destructiveHint: true).
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Send a booking request to the property (hotel, B&B, guesthouse or vacation rental) for a room or unit and dates. The resulting stay contract is directly between the guest and the property; Bookd is only the booking platform. Only call after the guest has confirmed the room, dates, guests, and given their name and email. Returns a booking_id and, when online payments are on, a payment_url for the deposit (card held, charged only if the owner accepts). Usually status is "requested": the request is emailed to the property (the guest is emailed when it answers) and the room is held until the owner answers or the request expires. Instant booking: for properties with instant_booking=true, Bookd checks the room live in the property's own booking system; if it is available, the booking is made there at once and status is "confirmed" (with the booking_id; the guest and property are emailed). With a deposit, the reply has instant_booking=true and a payment_url, and the booking is confirmed as soon as the deposit is paid (check booking_status). If the live check or write fails it stays a normal request; if the room was just taken, an error says nothing was booked. Only tell the guest it is confirmed when status is "confirmed". Not idempotent: each call creates a new request, so do not retry after a booking_id is returned (use booking_status). The guest pays the property directly; Bookd never handles guest money.
```

## Only reads (4)

Looks things up and changes nothing. Claude Code: allow.

### `booking_status`

- The name "booking_status" says "status": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read-only. Status of a Bookd booking by its booking_id (e.g. BKD-AB12CD3): requested, accepted (= confirmed, including instant bookings), declined, expired or cancelled, with dates, room and price. Returns no guest personal data.
```

### `check_availability`

- The description's first verb is "read": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read-only. Live availability for one Bookd property and dates (re-reads the owner's calendars first; nothing is booked or held), with room/unit prices, totals including any cleaning fee and taxes, cancellation policy and any deposit due.
```

### `get_property`

- The name "get_property" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Read-only. Full details of one Bookd property by its slug (from search_stays or a Bookd link): type, description, photos, amenities, house rules, check-in/out times, rooms or units (bedrooms, bathrooms, beds, cleaning fee) and prices from, taxes, cancellation policy and any damage deposit (held by the property).
```

### `search_stays`

- The name "search_stays" says "search": a word for reading.
- Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data.

Description, as the server wrote it:

```untrusted-server-text
Find independent stays bookable direct on Bookd (hotels, B&Bs, guesthouses, apartments, houses, villas, cabins) for a location and dates. Read-only: nothing is booked or held. Bookd properties come first: only properties with a room or unit free for every night are returned, cheapest first (exact town matches first), paginated. Each result has nightly price, total_price (incl. any cleaning fee and taxes), cancellation policy, bedrooms/bathrooms/beds for whole homes, any information-only damage deposit held by the property, and any deposit due (only when the property takes card deposits; otherwise the guest pays the property directly). If no Bookd property matches a location, the result has partner_results instead: links to partner hotels (accommodation only) on Trip.com and a Stay22 map for that place, dates and guests, with min_price, max_price, stars and currency applied. Partner hotels are not Bookd properties: the guest books and pays on Trip.com or the partner site, under that site's terms, and Bookd may earn a commission. Never call request_booking for them. Finding the partner city sends only the location text to Trip.com.
```

## Claude Code permissions

For `.claude/settings.json`, assuming the server is installed as `stays`:

```json

      "mcp__stays__get_property",
      "mcp__stays__check_availability",
      "mcp__stays__booking_status"
    ],
    "ask": [],
    "deny": [
      "mcp__stays__request_booking",
      "mcp__stays__cancel_booking"
    ]
  }
}
```

Capability tags behind the rules (a read tagged outbound is asked about):

- `mcp__stays__search_stays`: untrusted-input
- `mcp__stays__request_booking`: untrusted-input
- `mcp__stays__cancel_booking`: untrusted-input

- **high** Tools that change things, listed to anyone ([unauth-remote-writes](https://anlyon.dev/methodology#unauth-remote-writes))

```untrusted-server-text
The endpoint served tools/list without credentials, and the list has 2 tools that change things (2 destructive). Whether a call also works without credentials was not tested: tools are never called.

https://mcp.bookd.direct/mcp: tools/list returned 6 tools to an anonymous client, including request_booking (destructive), cancel_booking (destructive)
